TRUCK FOB RAILWAY VEHICLES.

Application filed September 30, 1927. Serial No. 223,049.

My invention relates to trucks for railway vehicles and has for itsobject the provision of an improved assembly between the arch bars ofthe truck side frames and the journal boxes whereby the bolts which areemployed for assembling the ournal boxes with the side frames arerelieved of shearing strain.

The invention has for its further object the provision of improved meansfor assembling the bottoms of the journal boxes with the tie membersthat are employed for pre venting the journal boxes from separating.

In carrying out my invention in the preferred way, anchoring plates areassembled with the bottoms of the journal boxes by means of bolts, theseanchoring plates being formed with fins which engage the journal boxesdirectly and prevent the anchoring plates'from having shearing effectupon the bolts. In the preferred embodiment of the invention, these finsare at the ends of the anchoring plates and are positioned to engage theinner and outer transverse bottom portions of the journal boxes, theanchoring plates, in effect, thus constituting sockets that receive thebottoms of the journal boxes and serve very effectively to relieve theaforesaid bolts of shearing strain. The bolts are preferably single orstraight bolts, each box being assembled by two sets of bolts whoselower ends are threaded into the underlying anchoring plate. Theseanchoring plates are formed with recesses at their mid portions whichreceive the tie members that are provided to prevent the bottoms of thejournal boxes from spreading apart.

The invention will be more fully explained by reference to theaccompanying drawing in which Fig. 1 is a side view, partially insection, illustrating the preferred embodiment thereof; Fig. 2 is abottom view of the structure shown in Fig. l; and Fig. 3 is aperspective view illustrating an anchoring plate and a tie memberassociated therewith in separated relation.

The truck illustrated includes an upper arch bar or compression member1, a lower arch bar or tension member 2, bolster columns 3 and 4, a yoke5 joining the lower ends of the bolster columns, journal boxes 6 at theends of the side frame, and tie links 7 which assemble the lower ends ofthe journal boxes with the yoke 5. The arch bars 1 and 2 are desirablyof rolled steel'converging toward theends of the side frame and whoseends are brought together above the journal boxes. These journalboxes'are assembled with the arch bars. by-means of the bolts 8 whichare passed downwardly through the outer ends of the arch bars andthrough the sides of the journal boxes '6.

The lower ends of these bolts are threaded.

and are screwed into the ends of the anchoring plates 9 which arearranged longi tudinally of the side frame. Each anchoring plate isformed with a mid recess 10 which receives the outer end of an adjacentlink 7, the inner end of such link being receivedin a recess in thebottom side of the yoke The bottom of'each journal box closelyapproaches the outer end offthe underlying link 7 so as to hold thislink end in its receiving recess 10. The bolts. are re lieved ofshearing strains due to fins1'1upon". the anchoring plates 9. These finsare preferably disposed at the outer and inner ends of the anchoringplates andsnugly receive' the cuter and inner bottom portions of thejournal boxes to prevent the plates from having shearing effect upon thebolts.

Changes may be made withoutdeparting journal boxes; upper and lower archbars.
